Systematic studies of several palladium complexes (Pd(OAc)2, [PdCl2(cod)], [Pd2(dba)3], [Pd(PPh3)4], [PdCl(SnCl3)(P{p-Tol}3)2], [Pd2Cl2(SnCl3)2(P{p-Tol}3)2]) as potential catalytic systems for arylation of vinylsiloxanes via Heck coupling reactions are described. Catalytic activity and selectivity were studied for a model reaction of trimethylvinylsilane with PhBr and m-ClC6H6Br and then the most effective systems were applied for functionalisation of tetramethyltetravinylcyclotetrasiloxane and poly(dimethylsiloxane-co-methylvinylsiloxane), leading to the silicone fluids having high refractive index (1.5–1.6). 相似文献

A new method for preparing neutral trichlorostannate complexes of PdII, based on the interaction between solid [PdCl2(MeCN)2] and SnCl2 suspension and a solution of an appropriate ligand in CH2Cl2, has been developed. The analogous method can be used to prepare complexes without tin, as well as compounds containing mixed anionic ligands. A number of complexes (including several new compounds) with amines, phosphines and diene ligands have been obtained by these methods. The procedures are simple and fast – the total preparation time (without recrystallisation) is ca. 30 min. 相似文献
